And -- big question this morning where will those Herman Cain voters go our headliner today hopes they felt straight to him. He's former Pennsylvania senator Rick Santorum. He spent more time in Iowa than any other candidate visiting all 99 counties and he joins me now sends -- thank you for being here thank you talking about Iowa. You staking your campaign on that you must've seen -- -- the de Moines register poll it's not encouraging 6%. -- salons it's. Well that's better than it was before me if you look at every poll we keep moving up moving up slowly but -- in the margin of error of both Rick Perry Michelle Bachmann. Both of whom and had enormous. Attention by the national media and have had money and resources Rick -- running literally millions of dollars in ads in Iowa. And he's he's right next to me in the polls I'm actually encouraged that the people of Iowa. As they as they go down to the to the end here start looking at all the candidates. We think we're gonna do very very we have a very strong consistent conservative message that matches. Better with I was anybody else. And we think we're gonna surprise lot of people. Talk about a strong consistent conservative message and don't -- -- Tuesday. Yes he does however we -- very concerned he lost his election in Pennsylvania by fans like twenty points he's not electable. Police had had a bit of a -- but not you -- that's that's a good thing. It's a great thing not to have had it we still have almost we have a month ago before the election you know -- -- a lifetime in politics cell. If you look at all these little boomlet they last about four to six weeks. Would -- and about week three. So we feel pretty good that you know come the middle of December and toward the end December. As candidates are looking for candidate they can trust someone that it's authentic someone who knows what they believe in and why they believe it. And -- has a record to back up the rhetoric as to what they wanna do to change this country because we do -- big changes. Well who's been Dillon has been out there has been -- -- fighting City Hall if you will and having success of doing it. It we've got -- good track record and I think that's gonna pay off in the end. Why do you have to be. Often January -- What is a good showing -- threshold well given everybody's it is seeing -- -- me to finish -- -- next to last obviously and to stay in the it's well I think -- -- -- I mean we need that we need to finish ahead of several candidates and I'd like I think -- I think we have a very good chance of -- and I -- people yes I do I really -- we've kind of he would say that wouldn't you know I believe it I really do I I I know when we were doing all sorts of phone calls and our office and and what we're hearing is that. Still 6070% of people on our still on the side -- you can read these polls. That's -- -- for the moment and as the latest polls is 11% -- but if you talk to people and they say you know who have you really you know -- are really committed. And they -- well no I mean we're still open to to other candidates. And again the cause we're making we're still hearing -- high percentage of undecided people still trying to find out more about the candidates. And remember this is a caucus not a primary you're talking about activists who -- gonna go out. We spent the time in the state we've talked to the activists we get people lined up to -- to be our caucus captains all these little caucus locations. About a third of the people that come to the caucuses come there and -- that's what that's what the -- have said. And we'll have people at those caucuses advocating for us because have been in their counting. They know my message that no one I -- one out want to accomplish it's been a strong message of pro growth -- values strong national security. And now I think that's gonna do well. Let me ask you about your family -- -- -- very public about 27 children now you've been very public can have been very emotional of course talking about you know younger with them. Who you said has basically a life as measured in in days and weeks less it it certainly is according to the to them the medical statistics but we've been very blessed and she's three and a half years of age. You know as with their last night get a chance -- -- -- -- -- she's an absolute -- she's the she's really the center of our life. And and we we feel so blessed to have an an as a mother. I just want how you can keep going and how you justified this with so much personal hall and at home well. As we all know even the pulls he had no I understand why don't worry about -- again I don't combat about the polls -- worry about what what I'm trying to do to be the best father and and the best husband I can be. And and obviously a big part of that is making sure that we have a country that respects her life. And a country that that is free and safe and prosperous for all of my children and I just felt like given this is. Really and I believe the most critical election in the history of the country. That I had to step up and make sacrifices like everybody does two to make our country a better country you obviously very committed to the conservative principles that you talk about however. It looks like you look at who's at the top -- they're not the most conservative the most consistent over the -- in in Iowa. Is -- something different about this election cycle I mean these consent -- and not gain the kind of traction that one might expect I. I think people -- persuaded more by what's who's getting attention then necessarily specific issues. I think people wanna -- -- when somebody can beat Barack Obama and that's and that's the focus so when people talk about when ability. You really have to look at the other candidates -- Newt Gingrich is always run -- -- heavily Republican congressional district in Georgia. And -- but at times to win that so if you're looking for somebody can pull together people and still be a conservative. I've got so let me -- about Newt Gingrich who's at the top of breakaway some 25% according to the Des Moines Register poll but in terms of social issues. He. You know has been married three times his two divorced is he's admitted to infidelity. Should -- -- hold that against him is that relevant. I think characters definitely an issue you know I I think they have to make a decision based upon. The person's entire record and and certainly character counts and I think you look at been married 21 years of seven children. That's a factor that people are gonna look at and and should look at when it comes to you know the the person you're gonna have to leave the country. This is not something just -- conservative with the social values and I think -- -- consistently put those in the let's say the back of the bus he's never really been an an advocate editor. Pushing those issues. I knew someone who likes to get issues that are eighty to 90% in the polls. An 8080% of the polls are generally not the necessarily conservative strong conservative issues but that's how it is has always tried to govern and and I respect that that's that's certainly a way to do so -- I I tend to take the position. It's important to leave with what you believe is right for American try to bring the American public along. Instead of trying to find where everybody is and then try to do that investment Herman Cain who obviously has dropped out and you hope to be the beneficiary -- -- all the candidates do. Was it inevitable did -- have to drop out -- these women came out of the woodwork. My heart went out to two -- -- all the candies for that what they have to go through and Herman's gone through very very difficult time for himself and his family and I think he made the right decision to two to go to leave for his family and for the country was clearly -- distraction that was not gonna go away and again I feel bad for -- I really do for him and for his family particular. And I hope that they can get well. Mitt Romney was the putative front runner. And certainly in -- it shows that in national election he would have the most electability. And get a lot of -- is -- saying that he's moved consistently. Conservative now. And on some issues more than than previous. -- -- there's no question that -- has moved. The question is you know what's this sincerity of the movement and whether it that he can be trusted and that's one of the reasons night talk so much about. You know -- looking at the candidate's record in determining. What the best best indication of what someone's gonna do in the future is what they've done in the past senate sometime thank you very much for me thank you Chris.
